Your pain may or may not have bee ovulation. Clomid commonly causes cyst formation, and that may have been what you felt. I do not have a good criterion for timing hCG in a Clomid cycle. I do not do it. We found adding hCG did not significantly improve pregnancy rates with Clomid. In fact, in our hands, Clomid pregnancy rates were so poor relative to other treatment protocols, I have not prescribed Clomid in almost 15 years. For more information, I invite you to see our web page, <www.texasfertility.com>.Good luck.

Using Femara for ovulation induction has not been approved by the FDA. It does work rather well, but an investigator in Canada raised the spectre of possible risk of birth defects. I have seen no evidence to indicate that it is an issue, but the manufacturer has notified us that if we use Femara for ovulation induction, and there is a problem, we are on our own. It does produce a degre of concern, when it comes to prescribing.
